What are the street names/slang terms for it?

What does it look like?

Cocaine is distributed on the street in two main forms: cocaine hydrochloride is a white crystalline powder and “crack” is cocaine hydrochloride that has been processed with ammonia or sodium bicarbonate (baking soda) and water into a freebase cocaine – chips, chunks, or rocks.

How is it used?

Cocaine can be snorted or dissolved in water and injected. Crack can be smoked.

The faster the absorption, the more intense the high. However, the faster the absorption, the shorter the high lasts. The high from snorting may last 15 to 30 minutes, while that from smoking may last 5 to 10 minutes. Cocaine’s effects are short lived, and once the drug leaves the brain, the user experiences a “coke crash” that includes depression, irritability, and fatigue.

What are its long-term effects?

High doses of cocaine and/or prolonged use can trigger paranoia. Smoking crack cocaine can produce a particularly aggressive paranoid behavior in users. When addicted individuals stop using cocaine, they often become depressed. Prolonged cocaine snorting can result in ulceration of the mucous membrane of the nose.
